To all whom/it mtg comma:

Be it known that .ROBERT E. WAGELEX,

deceased, late a. citizen of the United States;

did invent a certain new and useful Improvement in Calculating-Machines, of.

which the following is a full, clear, and exact description, such aswill enable others skilled in the =art to which it appertains to makeand use the-same, reference being had to the accompanyin drawin sforming part of this specificatihn, in which igure 1 is ,a sideelevational view showmg the frame andpart of the mechanism of s themachine; Fig. 2 is a vertical longitudinal sectional view through themachine; Fig. 3 is a side elevational view illustrating the position ofcertain parts when a key is depressed; Fig. 4 is a detail view of one ofthe key stops; Fig. 5 is .a detail view illustrating the lockingmechanism coiipera-ting with the stop bars; Fig. 6 is aside elevationalview of the escapementmechanism; Fig. 7 is a similar view showing theescapement mechanism in a changed position; Fig. 8 is a top plan view ofthe escapement mechanism; Fig. 9 is a top plan view of the machine withthe casing removed; Fig. 10

This invent-ion relates to a new and useful improvement in. calculatingmachines, the object-being to simplify the construction of a machineofthis character and reduce its cost'of manufacture, the variouspartslof the machine being stamped from sheet metal.

:The machine illustrated in [the accom partying drawings relates to thatclass of calculating machines wherein there is a traveling carriage.Thls traveling carriage rack bar of higher order. =When "the keys havebeen successively struck to introduce theproper example into-themachine, and the carriage with its slide bars locked in the positiondetermined by the controlling placing the first slide bar in the path ofa keys advanced so thatthe slide bars will co- I operate with therackbars of proper order,

a handle, preferably located at the side of the machine, is pulled bymanual power (or a motor may he employed to operate the machine ifdesired), so as to operate a bar,

'which bar coperates with the several devices of the machine toaccomplish the following: first, release the rack bars so that said rackbars will be moved to a position as determined by the slide bars intheir respective paths; second,release appropriate type hammers sot-hata. printing impresslon can be made from the type carried at the forwardend of the rack bars; and,.third, en-

gage the register-wheels with the rack bars,

all of this occurrin on the forward movement of the operatmg handle.On-the return movement of the operating handle, the carriage and itspositioned slide bars are restored to normalzposition; the rack bars arelikewise restored; the type hammers are restored; and, finally, theregister wheels are disengaged from the rackhars, when the machineis inreadiness for another operation. To obtain a total, a total key isdepressed, which causes-the re ister wheels to engage with the rackbarsefore the rack bars are released and permitted to move forward. Theregister wheels, offgcourse, ro-

tate until they are arrested by the zero stops,

after which and at-the end of the forward movement of the ogerating .barthe type hammers are release to make a record of the total. Bearwardmovement of the opcrating handle in taking a total may either restorethe rack bars when in engagement with the register wheels so. astoretain the total in the machine, which, under the circumstances, maybe designated as a sub-total,

:or the total key may be permitted to rise,

which will disengage the register'wheels from the rack bars T so thatsaid register wheels will stand at zerov and the machine be clearedbefore the rack' bars are restored.

To repeat a number in the machine,that is,-

add the same number introduced into the machine a number of times in theregister, a

repeat key arranged on the operating handle is depressed, and theOperating handle pulled the necessary number of times after an examplehas been introduced into the machine.

through the keys. The repeat key'prevents the slide bar carriage frombeing restored on the rearward movement of the operating bar, andconsequently the positioned slide bars successively cooperate with therack bars. a

The keys and key st0ps.-In the drawings, 1 indicates a base upon whichare ar-' ranged two side frames 2. 3 are the, digit keys numbered from 1to 9 7 inclusive, see Fig. 9, whose bars are provided with appropriatepivots arranged in a suitable hearing bracket 4 mounted on the base, seeFigs. 2 and 3. 5 indicates a transversely arranged bar-under the keybars '3, which ar 5 is mounted upon a lever 6. Each of the digit keys 3has its bar cooperating with the crank end of a rockshaft 16, see Fig.4. The

inner end of each rock shaft isprovided' I with an arm connected by alink 17 to a stop 18. The stops 18 of the several digit keys arearranged in proper order-in a guiding frame 19, which guiding frame ispreferably provided with tapering openings so as to accommodate thearcuate movement of the stops 18. There are ten stops 18 capable ofbeing positioned respectively by the zero and the digit keys. The zerokey, which is practically a space key, positions the rearmost stop whichis coincident with the. particu- 6, which is marked6, carries escapementi-pawls 7 and 7 cooperating with an escapement wheel 8 arranged on avertical shaft 9. The operation .of the escapement mechanism is clearlyshown in Figs. 6, 7 and 8, wherein it will be seen' that when the rearend 6 of lever 6 is raised, upon the depression'of a key, the escapementpawl 7 whose face is slightly in front of the face'of the pawl 7,, isbrought in' front of one ofthe teethbf the escapement wheel 8 andpermits said wheel 8 to rotate slightly, possibly the distance of halfof one of the escapement teeth. This locates the pawl 7 on top of theescapement tooth, and when the key 3 is released ,a spring 6 connectedto the ,rear arm 6 of the escapement lever, will pull the arm '6 down,causing the pawl 7. to

drop beneath and release the escapement tooth, the pawl 7 being thrownin front of the next escapement tooth.

From the above itwill be seen that the movement of the escapement wheeloccurs after the digit key has been released, and, except for the slightmovement incident to the difference between the operating faces of thepawls 7 and 7", it may be said that the escapement wheel remainsstationary duringv the time that a digit key is bein depressed. Theinner faces of the pawls are preferably beveled, and these pawls areheld in normal position by a connecting spring 7", the normal positionof the pawls being de-. termined by a bent end 6 of the escapementlever. When the escapement wheel is restored to its home position, thesepawls 7 and 7 a may be vibrated to permit the teeth on the escapementwheel 8 to pass there-' through. The escapement wheel 8, as shown inFig. 8, is mutilated, that is, said wheel has a blank untoothed space sothat it is possible for the escapement wheel to be reversely rotatedbeyond its starting position, for purposes which will hereinafter bedescribed. I A

The traveling 0arrz'age.Shaft 9 to which the escapement wheel 8 fixed,carries at its upper end a gear 10 meshing with a rack 11" mounted onthe underside of a slide bar carriage 12. The carriage 12 isprovidedwith rollers 13 operating upon" tracks 14: supported by the side frames2. A spring drum 15 is connected by a cable or flatsteel tape tothecarriage 12, see Fig. 9, and. tends at all times to pull the carriage 12toward the left, looking from the front of the machine.

The spring drum 15, when permitted to do, so,.restores the carriage tooperative position, in which the face of the pawl 7 engages the firstescapement tooth.

Releasing the slide bars.Coincident with the positioning of one of thestops 18, the

depression of the escapement bar 6 will cause a lug 20, mounted in asuitable arm pivoted at the rear end of the guide 19, to be depressed byreason of a link connection between said arm and the escapement bar 6through the medium of the link' 21.

This lug 20 cooperates with the finger 22 of a locking detent 23, whichdetent isdesigned to engage notches preferably in the form ofratchet'teeth on the underside of the'slide bars. The detents 23 aremounted in suitable bracket extensions arranged on the carriage 12,appropriate springs being provided to cooperate with said detent-s toforce them into engagement with the teeth of the slide bars. There is anindividual detent for each slide bar in the carriage. As the lug 20 isdepressed, the detent 23 releases its complementary slide bar andpermits said slide bar, which is marked 24, to move forwardly under theimpelling action of aspring 25,

. until arrested by one of the positioned stops 18. When the digit key,or-the zero key, as

the case may be, is released, the lug 'is also released so that thedetent 23 engages the proper tooth of the slide bar to. hold said slidebar in the position inwhich it was arrested by the stop 18. In orderthat this release and reengagement of the slide-bar by the detent 23 mayoccur in proper time relation to the movement of the digit key and itsoperated stop 18, a clearance space is left between the lug 20 and thefinger 22 of the detent, which clearance space is also necessary topermit the lateral movement of the detent with respect to said lug.

It will be noticed that a stop 18 mustbe raised and in position toarresta slide bar before the detent 23 is operated to release the slidebar, and when the digit key starts to rise the stop 18 will start tomove downwardly, but before the stop 18 is housed in its guide-Way thedetent 23 will have reengaged its slide bar so as to lock the same inits arrested position, the final movement of the lug 20, after it hasreleased the finger 22,

in reaching its clearance position, being consumed in finally housingthe stop 18.

The operation of'the above-describedpart-s of the machine willundoubtedly be understood fromwhat has been said, but to recapitulatebriefly it may be said that when any of the digit keys are pressed theslide bars 24 will move forwardly until arrested by the stops 18, thecarriage 12 being. held practically stationary during this operation;that when the key is released the detent 23 will reengage with itspositioned slide bar before the stop 18 is retracted, and before theescapement pawl 7 a has released the escapement wheel 8; consequentlythe positioned slide bar is locked in its-forward position before thecarriage 12 takes a step toward the left, and that the final upwardmovement of the 'digit key, will depress the pawl 7 a so that thecarriage will take one step to the left, placing under the control ofthe stops 18 the next adjacent slide bar tobe positioned in a likemanner upon the operation of another digit. The successive depressionsof 'the digit keys or of the zero key, as the case .may-be, willsuccessively advance the carriage step by step toward the left until thenumber to be introduced into the register wheels has been struck on thekeys, when the parts arein readiness for the handle-pull.

The rack bars.26 indicate the rack bars which are guided in theirmovement in any suitable manner, those shown in the drawings beingprovided with slots through which pass supporting rods 27. These rackbars carry independently movable type 28 at their forward ends, theforemost of which type bears the zero character, and the remainderfigure characters from 1 to 9 inclusive. Normally the zero character isin printing line under a platen 29, which platen supports a sheet ofpaper.

Any appropriate paper-feeding devices maybe employed in connection withthe platen 29, and means may also be used to adjust this platenlaterally so as .to print difierent columns on the same sheet of papersupported thereby, in a manner well known in this art, ifsuch isdesired. Each of the rack bars 26 is impelled forwardly by. a spring 30connected thereto. A pawl or lipped plate 31 mounted on a rock shaft 32and common to all of the depending fingers on each rack bar, preventsforward movement of the rack bars. hen the shaft 32 is rocked so as todepress the common restraining plate or pawl 31, the rack bars arereleased and may be moved forwardly. a

33 is a restoring bar located in front of the depending extensions ofthe rack bars, and which restoring bar also prevents forward movement ofthe rack bars except when the operating rod, to which the restoring bar33 is connected, is moved forwardly.

The rack bars 26 are provided with rack teeth which .are designed tomesh with the register wheels, and each rack bar is also provided with anotch into which fits a pawl identified with the printing mechanism tobe hereinafter described.

As the restraining plate or pawl 31is common to all of the rack barsand, when operated, will release all of the rack bars simultaneously, itis obvious that some means must be provided to permit only those rackbars to move forward which are active, that is, which are identifiedwith the orders comprehended by the number in troduced into the machinethrough the keys.

Thus if the first and second rack bars at the right were identified withthe cents and dimes columns, and the remaining rack bars toward the leftwere identified with the units dollars, tens of dollars, hundred ofdollars, etc., columns, it is obvious that if $5.25 were introduced intothe machine through the key board, which is equal to 525' units, thefirst three slide bars 24 at the left would be positioned in the fifth,second and fifth positions, respectively, in the paths of the firstthree rack bars at the right. When the operating handle is pulled therestraining pawl or plate 31 is depressed so as to release all of .therack bars,.and the I restoring bar 33 moving forwardly with theoperating handle will permit all of the rack bars to move forwardly, thefirst three bars v at the right will permit it being arrestedat' thefifth, second and fifth positions, respectively, while the other rackbars would,

if means were not provided to prevent them,

move to the ninth position. The traveling carriage is, therefore,provided with pivoted arms 34, see Figs. 2 and 9, which arms carry a rod35 having a plate 35 normallylocated in front of the. dependingprojections at the rear ends of the rack bars.

Thus, if the carriage 12 is advanced three spaces toward the left, theplate will be -moved a corresponding distance and will that when thetraveling carriage is home the projections of therack bars 26. To permitplate 35 lies in front of thedependingprojections of all of the rackbars. When,

however, the plate 35 advances one step 0 with its positioned slide bar,the plate 35 will release the first slide bar at the right andsuccessively releases other slide bars of higher order as the carriageadvances.

In view of the fact that the plate 35 iscarriedby the carriage 12, itwillbe obvious that when said carriage is restored the plate 35 might,by the restoring movement of the carriage, be moved behind the dependingthe rack bars to be restored in their proper time relation to the otherparts of the machine it is preferred to hinge the lower portion of thesedepending projections of the rack bars, such hinged portions .26 beingconnected to the rack bars bya rule orelbow joint which permits offorward movement but (prevents backward movement. Should anyofjthe rackbars not be restored at the time the plate 35 moves to a position behindthem it will be seen that the hinged portion 2 a will yield and permitfull restoration of the rack bars; Should the rack bars be in positionto interfere with the movement of the plate 35, thensaid plate willyield until the rack bars are fully restored, when spring 35, connectedto the bar 35, will cause the plate 35 to move into position in front ofthe hinged portion of the rack bars. The springs which hold the hingedportions of the rack bars in osition are sufiiciently' strong to causethe said hinged portions to depress the pawl 31, and said springs willyield when said hinged portions ride over the plate 35. The bar 35 ispreferably square so that it is per- 1,oso,975

mitted longitudinal movement in its bearings, but prevented fromrotating.

The operating bar..Referring to Figs. 9 to 12 inclusive, 36 indicates anoperating bar mounted in suitable bearings on, one of the side frameplates 2, preferably the righthand frame plate, but it is obvious thatthis bar and its carried handle could be on the left-hand side of themachine if desired. This bar 36 is provided with keys fitting inkey-ways therein and in its bearings, which keys permit longitudinalmovement of the bar but prevent any rotary motion being impartedthereto. The restoring bar 33 is supported by the bar. 36, preferably atits rear end. A spring 33* is coiled about the bar 36 in advance of thebar 33, so that said bar 36 may have a slight ext-ra'movement after therack bars have been restored to their full home position by therestoring bar 33, which extra movement is necessary to disengage theregister wheels from the rack bars, and whichdisengagement must occurafter the rack bars are stationary and at home. A stop pin 33 isprovided on the bar 36to determine the fixed position .of the restoringbar with respect to the bar 36, and some appropriate means must, ofcourse, be provided, such as a key in the bearing of the restoring bar,to support the restoring bar in its horizontal position and yet permit aslight movement of said restoring bar longitudinally the bar 36. Bar 36also has. a yielding latch spring 37 which cotiperates with a stud orpin 38 on the rock shaft 32, wherebyas the bar 36 moves forwardly therestoring bar 33 is permitted a slight independent movement before. theshaft 32 is rocked and the selected rack bars released. A spring 32 ontherock shaft causes the pawl 31, after the selected rack bars have beenreleased, to assume its normal position, and. on the rearward movementof the bar 36 the latch spring 37 yields with respect to the pin or stud38, and thus enables the latch spring to pass behind the pin or stud inreadiness for anotheroperation. Bar 36.

is provided with a handle 39 designed to be grasped by the operator,which handle has a slight rotary movement on the bar and is normallyheld in its forwardosition by means of a spring 40, which spring tends'to p pull the bar 36 back to its home position after operation. The sideframe 2, as

shown in Fig. 1, is slotted for the passage of the operating handle 39,and the rear upper edge of the slot is formed with an enlargement intowhich the handle 39 oper: ates, giving the handle a slight upwardmovement as it approaches its home position. In pulling the handleforward the operator slightly depresses the same in order that it maypass the shoulder occasionedby the enlargement.

Restoring the slide bars.Bar 36 carries mea re 36 is home the bail 42 isrocked and the roller 43 elevated out of the paths of the slide bars 24.

When, however, the bar 36 is moved forwardly the heel portion 42* leavesto normal position,

by dotted lines in Fig. 10.

the pin 42*, and the roller 43 carried by the free end of the bail isfree to ride on the slide bars in its forward movement, and drop infront of the positioned slidebars 24 when in its forward position, sothat when the bar 36 is moved rearwardly to its home position all of thepositioned slide bars 24 will be moved rearwardly by the roller 43 andrestored the detents 23 yielding to permit this. When the bar 36 ishome, the heel portion 42 is in engagement with the pin 42 and theroller 43 is lifted out of engagement with the slide bars 24, as shownOf'course, when the repeat key is operatedmeans are provided to preventthis restoring bail from restoring the slide bars, as will hereinafterappear.

Restoring the traveling carriage-Referring to Fig. 17, it will beobserved that the gear wheel 10 at the upper end of the escapement shaft9 meshes with a rack 44, which rack is held in position and guided byslot and pin connections, the pins being supported by the track rods 14.Rack 44 is connected to a plate 44* supported by suitablerollers mountedon the side frame 2,

which plate 44 is provided with.ratchet teeth 44 at its rear edge.

45 indicates an extension carried by the bar 36, upon the lower end ofwhich exten forward sion is arranged a gravitating pawl 46. A pin 47 isarranged in the frame plate 2 so as to engage the upper face of pawl 46and raise said pawl out of engagement with the teeth 44*. Thus, when thebar 36 is home and the pawl 46 is raised, the gear wheel 10 may rotatestep by step, advancing the carriage 12 to the left and the plate 44forwardly, the teeth 44 moving under the pawl 46.

Whether the carriage is stepped once to the right or up to the fullcapacity of the machine, which in this instance is 9,999,- 999.99, nineorders meaning that the car riage may be stepped to nine differentpositions leftwardly, the plate 44 willbe stepped forwardlyproportionately, and, regardless of the position of the carriage orplate, the pawl 46 will be released when the bar 36 is moved forwardly,and will, at the extreme When 'vided at one end osition of bar 36,engage one of' the bar 36 is moved rearwardly, the pawl 46 in engagementwith one of the teeth 44 will restore the plate '44" and rotate the gear10, which in turn is meshed with the rack 11 on the carriage 12, andconsequently the rearward movement of bar 36 will restore the carriage12 to its home position. As the bar 36 approaches its home position andafter the carriage 12 has been fully restored, the pawl 46 is elevated,as shown in Fig. 1, whereupon a slight excess movement imparted to thecarriage in restoring it home, to take up possible wear or lost motionin the parts, will be absorbed by the spring drum 15 which moves theescapement wheel 8 so that its first tooth will engage the escapementpawl 7, the blank in the escapement wheel being provided for thispurpose as heretofore referred to.

Register nwokzmz'sm.'lhe gear .wheels comprising the register mechanismare normally out of mesh with the racks 26, but after the racks havebeen positioned by the slide bars 24 it is necessary to engage theseregister wheels with the racks so that when the racks are restored bythe restoring bar 33 the gear wheels will be rotated a distance ofone ormore teeth depending upon the position of the rack bars. Each registergear wheel has twenty teeth, and according to the decimal system when anumber exceeding 9 has been introduced into any gear wheel means must beprovided for carrying from a gear wheel of lower order to a gear wheelof higher order. This will be described later.

49 indicates the register gear wheels, each gear wheel being looselymounted on a stud shaft carried by 'a plate or bar 50. The ends of eachplate 50 are provided with slots, through the rearmost of which passes abar 51 supported from theside frames 2, and which bar acts as a pivot onwhich plates 50 may swing.-

52 indicates a rock shaft carrying a bail formed in part by a rod 53which passes through the slots in the forward ends of the plates 50.Suitablewashers may be strung on the rods 51 and 53 for the purpose of.

spacing the plates 50 a proper distance apart and preventing theirdisplacement. The plates 50, however, are left free so as to moveforwardly or backwardl in eflectin the'carrying. Rod 52 is provi ed atone en with a rock arm which is connected by a link 69 through a slotand pin connection to an arm'7l on a stud shaft 72. Rod 72 is pro- 10,which tappet cooperates with projections 52? and 52 on the operatin bar36. When the operating bar is moved orwardly as shown in Fig. 10 therearmost projection 52 engages the tappet 52* and rocks theshaft 52 soas to raise the forward ends of plates 50 and cause the register wheelsto mesh with the racks. The gear wheels re with a tappet 52*, see Fig. i

register wheel main in mesh with the racks until the oper- I and alsowith a spring-pressed centering pin 55. In the position shown in Fig. 1,the bar 36is home,-and as the bar is moved forwardly the projection 52engages the tappet 52*- and positively rocks the segment until thespring 54 has passed a position of dead centers, when said spring willthen utilize its energy to raise the register gear wheels 3 intoengagement.with the racks, in which position the centering pin 55 willbe located in the-forward notch ofsegment 53*. The.

reverse action takes place when the operating'bar is moved rearwardlyand the projection 52 cooperates with the tappet 52 Carryingmeoham'sm.-As stated before, whenever any register wheel is rotated byits cooperating rack a distance of ten teeth or more, means must beprovided for carrying from the next adjacent .wheel of higher order.This is accomplished by providing each register wheel, except the one ofhighest order, with two'trip ing projections 56. It will, of course, beun erstood that if the 7 had ten teeth there would be but one of thesetripping projections; or

' if theregister wheels had thirty teeth there would be three of thesetripping pro ections,

said tripping projections being located at every tenth tooth.

57 indicates a tripping the plate 50 which carries t awl mounted on eregister wheel,

' with whose tripping projection said trapping pawl 57 coiiperates.Asthe tripping pro ection passes this tripping pawl it depresses itsforward end and raisesits rear end, which rear end is located under aprojection 58 of a restraining pawl 59. These restraining pawls aremounted on. a cross bar 60, and each restraining pawl is held with itsrear .end depressed by means of a spring 61, which spring isalsoconnected to a plate 50,so as to move said plate 50 forwardly; Eachplate 50, with the exception of the one at the'extreme right looking vfrom the front of the machine, 1s provided with a rojectionor shoulder62 which normally res behind the rear end of the restraining pawl 59.Whenever the tripp ng pawl 57 is operated by .a tripping pro ec- 'tionitscooperating'restraining pawl 59 is lifted, which releases the plate50 carrying the next adjacent register wheel of higher order, and thespring 61 moves said plate and its register wheel forwardly a distancepermitted by the slots in-the ends of said actuated plate. As the plates50 are tripped only when the register wheels are in mesh with the racks,it will be observed that the movement of plate 50 will cause its carriedgear wheel to rotate, and the rotative movement thus imparted to thegear wheel is equal to the distance of one tooth.

- From the above it will be seen that thedisplacement of the plate 50and its carried register ear wheel may occur either when said registerwheel is in mesh with a stationary rack or a moving rack, during theperiod of restoration of said rack. This,

however, will not affect the relative displacement between the wheel andthe rack, and whether the rack is stationary or moving the wheel willeventually either rotate itself, if the rack is stationary, or berotated by the rack a distance of one tooth in excess of the movementimparted to the wheel, shouldthe rack be moving. Thus at all times theregister wheels stand fully carried, and it is not necessary, as in sometypes of machines which have been on the market, to impart an extrastroke. to the handle to eifect the operation of carrying. In fact, itwould be possible to obtain a correct total from the register Wheelswithout replacing the register wheels to their original positions as thezero-determining element, to

wit, the tripping pawls 57 move with their respective register wheels,and the register wheels when meshed with the racks to yield a totalwould insure proper movements of the racks irrespective of the fact thatthe register wheels might stand displaced at the time the total wastaken. However, it is preferred to replace the register wheels to theiroriginal positions after they have been disengaged from their respectiveracks, and at the end of the rearward movement of the operating bar 36,and this is accomplished by means ofthe rock shaft 41 heretoforedescribed, which rock shaft, or a sleeve 4:1 on the rock shaft, en ageswith depending project-ions on the Eorward ends of the plates 50 andrestores any displaced plates 50 to their original position. This ispermissible because the tripping projections 56 on the register wheelsare tapered to a point, and after operating the. tripping pawls 57 saidpawls and their controlled restraining pawls, assume their normalposition.

To prevent movement of the register wheels when out of meshwith theirrespective racks, I mount locking devices 63 on the plates 50, theforward ends of which looking devices are slotted .and held in properposition by the bar 64; supported from the side frame plates 2. A tooth63 is arranged at the forward ends of each locking device so as toengage its complementary register wheel. .The object in providing aseparate locking device'for each wheel is to lock said wheels againstmovement when disenga ed from their racks, notwithstanding the act thatsaid wheels may at the time be displaced. This locking device, movingwith the wheel, will," of course, keep the wheel locked, not only whileit is displaced but during the time it is being replaced and after it.has been replaced, and while it is still out of engagement with theracks.

Taking a t0taZ.-Referring to F igs. 1 and 18, 65 indicates a total keyor lever which is preferably mounted in the bracket bearing 4. Thistotal key coiiperates' with a bell crank lever 66, which in turn isconnected to a link 67. Link .67 is connected by a slot and pinconnection to a bell crank lever 68, in turn connected by a slot and pinconnect-ion to the link 69 heretofore described.

By referring'to .Fig. 1 it will be observed thatin the ordinaryoperation of the machine the slot in the lower end of link 69 Ipermitsthe link 69 to be vibrated without disturbing the lever 68. Whenthe register gear wheels are out of mesh the pin in the end of bellcrank lever 68 is located at the upper end of the slot, and thus link 69can be raised independently of the bell crank lever 68. When the totalkey isdepressed and therearwardly extending member of bell crank lever68 is raised, the .l-ink'69 will be raised with it so as to cause theregister gear wheels to mesh with the rack bars.

This upward 'movement, however, of link 69 does not disturb the positionof the rock arm 7 1,'the tappet 52 or the notched segment 53. Againreferring to Fig. 1, where the parts are shown in normal position, it

will be observed that the pin carried by the slot in the end of arm 71,which slot is necessary on account of the arcuate movement of the arm,the lower end of the link 69 being connected to the bell crank lever 68,normally occupies a position atthe upper end of th'eslot in the link 69in readiness to directly operatesaidlink when said arm-71moves upwardlyand in a position to permit the link 69 tomove upwardly w thoutoperating said arm 71, as when said link is'operated bythe bell cranklever 68. By this construction, in the normal operation 'of the machine,as in introducing examples intothe register, the-register is thrown intoengagement with its racks at the extreinit of the forward movement ofthe bar 36,.

and out of engagement with its racks v at the extremity of the rearwardmovementof the bar. However, in tak-in a total, it is necessary to throwthe register into engagement with-the racks; before the bar '36 is movedforwardly, and this is done by the mechanism above described. When theregister is in engagement with the racks b operating the t6ta1 key asabove descr be preaches the ,when the bar 36 is andathe bar 36 .is movedforwardly, it will be seen that the register wheels will be reverselyrotated until the tripping pawls 57 come in contact with the trippingprojections 56, at which time all the register wheels will stand atzero, and the rack bars will indicate the total registered in theregister. The type in the printing line] will be positioned to printthis total when the type hammers are released'as the bar 36 apforwardlimit. of its movement. 7 g

Clearing the machine-If it is desired to clear the machine it is onlynecessary, after pressing the total key down, and pulling the bar 36forwardly, to release the'total key in its forward position, when theregister wheels will be disconnected from their respective racks. Itappet 52?, as shown in Figs. 12'and 12 is pivotally mounted in the endof the stud shaft 71, and its lower \end'is lifted by a projection 68 onthe bell crank lever 68 when said bell crank lever is raised. Thus, whenthe bell crank lever 68 is operated, the tappet 52 is thrown out of thepath of the pro ection 52, asshown in'Fig. 12, and the bar 36 maybepulled forwardly and not rock the stud shaft 72. The release of thetotal key, when the rod 36 is in its forward limit of movement, likewisereleases the tappet 52, which is returned by a spring The 52 to itsnormal position. When the projection 52 is in the path of the tappet, itis obvious that the spring will yield and restore the tappetto normal,operative position, after the handle bar 36 starts on its backwardmovement. By disengaging the register wheels from the rack bars, whenthe handle bar 36 is forward, all of the register wheels stand at zero,and the rack bars may be returned to normal position, without actuatingsaid register wheels.

, Retain-mythic total in the ma-cht'ne.To retain the total in themachine it is only necessary to hold the total key down, and by so doingkeep the register wheels in mesh with their respective racks during thebackward movement of the bar 36, which will result in causing the racksto operate the register wheels to the position they occupied before thesub-total was printed.

Releasing the rack bars and obtaining a Fig. 18, from said bracket arm34 cotiperates with the cam face on the link 67, and when said link ismoved rearwardly.- its cam face engaging the part7?) depresses the rod35 and ermits all of the rack bars to move forward ly. Link 67 is alsoprovided with a slot *inits rearv end which engages the pin on a rockarm 32 on rock-shaft 32, and by I machine through; the key board to addsaid number in the register a number of times, a

repeat key 7 arranged adjacent the operating handle 39 is depressed.This repeat key (see Fig. 11) is mounted on the bar-36 and is; ca ableof slight rotation on said bar. Key" 4' is only operated after anexample has been setup int-he machine and the traveling carriage hasbeen advanced to the left with its slide bars properly positioned and inthe register wheels indicated by the's'lide.

locked in position as herein before described.

'When the carriage is-so advanced and it is desired to successivelyregister the numberf bars in the carriage, it is only necessary toprevent restoration of the slide bars 24: and

the carriage 12, and this is accomplishedwith respect tothe former bymeans of a finger 75 which coiiperates with. one of the bail pieces 42and holds the restoring bar 43 in its elevated position,.so that itcannotrestore the slide bar 24 to position; and

' with respectt-othe latter, a pivoted member 76' connected to therepeat key bears upon -said pawl in its raised position the forward endof pawl 46 so as tohold out of engagement with the teeth 44 Thuswhen therepeat key is depressed, neither theslide .bars 24 nor the carriage 12can be restored, 'and consequently aslong as the repeat key is helddepressed and the barv3 6operated, the number-indicated by the slidebars may beregistered adesired number of times in the register wheels,depending upon the number of strokes imparted, to the bar 36.
